According to this new (in Spanish) federal court decides implementation of COVID passport
The magistrate of the Supreme Federal Court of Brazil decided it will demand proof of vaccination for international travelers entering Brazil. And that formerly it demanded mandatory vaccination with the possibility of imposing restrictions on those who didn't vaccinate.
How is this possible? In other countries I know this kind of decision belongs to the executive branch. Also in the past, I've read Brazilians stating the judiciary was "creating law" and assuming functions of the legislature by re-interpreting the text of the constitution saying something the constitution didn't say at all.
How can the judiciary make executive decisions in Brazil? Is this something assigned in the constitution, or is the judiciary exceeding its authority, and if it's so, how is it that other public officials obey them?
